DETAILED DESCRIPTION

Overview

Network functions virtualization (NFV) can be employed to virtualizecomponents (e.g., nodes, switches, interfaces, etc.) of a network,wherein virtual machines located in a cloud or virtual environment canperform processing that was previously performed by custom hardwaredevices these virtualized components replace in an NFV architecture.These virtual machines can be readily instantiated or destroyed in thecloud with very little effort and represent a separation of hardwarefrom software. In other words, NFV can be implemented in connection withcloud-based computing instead of requiring localized custom hardware toperform the same functions—hence, the network functions being executedare no longer tied to custom hardware.

As noted, there are advantages to implementing a network according toNFV architecture. For example, since NFV represents a separation betweenhardware and software, virtual environments can be constructed byservers or other devices that are physically located substantiallyanywhere in the world instead of being tied to a specific location, asis the case with previous network architectures. For instance,traditional hardware tasked with providing a service to network userswas generally tied to a physical location associated with that serviceor a related network element. In contrast, this same service can beprovided by leveraging a virtual environment that is constructed bydevices that are not tied to any specific physical location. Moreover,the devices can be commodity-based servers rather thanapplication-specific custom devices and hence less expensive to operateand maintain.

However, separating hardware from software in connection with networkfunctions, which represents an advantage that is provided by NFV, alsointroduces challenges that are not present for many other types ofnetworks. In this regard, generally due to the fact that NFV operates toseparate hardware and software elements, identifying the locationassociated with a specific device represents a distinct challenge.

The disclosed subject matter relates to a referent system that can beutilized to identify a precise physical location of devices associatedwith NFV networks. Such can be advantageous for a number of reasons. Forexample, consider the case in which a network device of a traditionalnetwork fails. Typically, such was remedied by dispatching servicepersonnel to repair or replace the failing network device, which oftenrepresented a significant expense and possibly interrupted service for asignificant amount of time. Historically, however, due to the tightcoupling between hardware and software elements of traditional networks,these service personnel generally knew which failing network devicerequired service and knew the location of that device.

Now consider a similar example in which a network device thatinstantiates a network function in a virtual environment associated withan NFV network. Suppose an error of some type occurs and the networkfunction does not execute as intended. One of the advantages of an NFVnetwork is that the network function can be moved and/or re-instantiatedand executed by other devices of the network, generally without anyinterruption to the service and at virtually no cost. However, if theerror occurred due to hardware failure or the like, service personnelgenerally do not have a good idea which physical device is failing andneeds service, largely because there is no tight coupling betweenhardware and software elements, as is the case for traditional networks.

A given building might have many floors, each with many aisles ofcomputing devices that operate in connection with the network. Each ofthese aisles might have many device bays, and each of the device bayscan have multiple shelves, and within each shelf, multiple devices thatcan execute the network function. Such can be a difficult undertaking toidentify which device, from among potentially many thousands, requiresservice. Such a difficulty can be further compounded by the fact thatmany such buildings might exist, distributed at various locationsthroughout the world.

Another advantage provided by the disclosed referent system can relateto selecting devices at specific locations for instantiating networkfunctions. Consider a network service that critically requires lowlatency between various interoperating network functions. As anotherexample, consider a network service that has very stringent regulatorydemands relating to that service or the underlying equipment. In theseand other cases, the referent system can be used to select specificdevices that are used to execute a particular network function. Forexample, devices in very close geographic proximity can be selected toexecute interoperating network functions that have low latencyconstraints or devices at a very specific location can be specificallyselected to execute network functions in order to accommodate regulatoryor other constraints.

NFV Referent System Architectures

The disclosed subject matter is now described with reference to thedrawings, wherein like reference numerals are used to refer to likeelements throughout. In the following description, for purposes ofexplanation, numerous specific details are set forth in order to providea thorough understanding of the disclosed subject matter. It may beevident, however, that the disclosed subject matter may be practicedwithout these specific details. In other instances, well-knownstructures and devices are shown in block diagram form in order tofacilitate describing the disclosed subject matter.

Referring now to the drawing, with reference initially to FIG. 1,network device 100 is depicted. Network device 100 can provide for areferent system (e.g., referent system 108) indicative of a geographicalor physical location of devices associated with an NFV Network 101. Insome embodiments, the referent system can be associated with a networkfunction so that a precise physical location of the device executing thenetwork function can be determined. In some embodiments, the referentsystem can be leveraged to select a device to be used to execute anetwork function, for instance selecting a precise physical locationthat is to be the location of devices executing the network function.Generally, network device 100 can comprise a processor and a memory thatstores executable instructions that, when executed by the processor,facilitate performance of operations. Said processor and memory, as wellas other suitable computer or computing-based elements, can be used inconnection with implementing one or more of the systems or componentsshown and described in connection with FIG. 1 and other figuresdisclosed herein.

Network device 100 can be configured to execute network function 102according to one or more NFV protocol(s) 103. For example, NFVprotocol(s) 103 can define rules relating to functions of a NFV network101 being provided in virtual environment 104. In some embodiments,virtual environment 104 can be generated by network device 100 or bymany network devices, including network device 100, associated with theNFV network.

In some embodiments, network device 100 can associate network function102 with referent identifier data 106, which can be identifier datadefined by referent system 108. Referent identifier data 106 cancomprise device data 110 and reference data 112.

Device data 110 can specifically identify network device 100. Hence,device data 110 can be used to identify the device (e.g., network device100) that is executing network function 102. Additionally oralternatively, device data 110 can be used to select a specific device(e.g., network device 100) to execute or instantiate network function102. In some embodiments, device data 110 identifies network device 100relative to other equipment 114 associated with the NFV Network 101,which provides certain advantages over other identification techniquessuch as utilizing media access control (MAC) address data or the like,as further detailed herein. As used herein, other equipment 114 iscontemplated to include any suitable equipment related to the NFVnetwork 101 other than network device 100, which can be identifiedrelative to the other equipment 114.

Reference data 112 can represent data that identifies the otherequipment 114. In some embodiments, referent identifier data 106 canindicate a physical location of network device 100 and the otherequipment 114. FIG. 2 illustrates various examples of other equipment114, FIG. 3 depicts an example of a hierarchical referent system 108 inconnection with other equipment 114, and FIG. 4 depicts an example ofreferent identifier data 106 that is defined by referent system 108, allof which are intended to be referenced in conjunction with FIG. 1.

Turning now to FIG. 2, illustration 200 is provided. Illustration 200depicts various examples of the other equipment 114. For instance, otherequipment 114 can relate to building structure 202 or a floor structure204. In those cases, the associated referent identifier data 106 canidentify the particular building structure 202 as well as identify aspecific floor of the building associated with floor structure 204 thatgenerally includes devices associated with NFV network 101. Additionallyor alternatively, other equipment 114 can comprise an aisle structure206 that can comprise a group of devices associated with the NFV Network101, a bay structure 208 that can comprise a group of devices associatedwith the NFV Network 101, a shelf structure 210 that can comprise agroup of devices associated with the NFV Network 101, or any othersuitable structure or device. It is understood that other equipment 114can represent substantially any equipment associated with the NFVNetwork 101 or any structure or housing that comprises devices such asnetwork device 100 that execute network functions of an NFV Network 101.Hence, the examples provided herein are referred to by convention, butother conventions or terminology is contemplated and, where suitable, isconsistent with the disclosed referent system 108 and/or other disclosedsubject matter.

FIG. 3 provides a graphical depiction 300 of an example referent system108 that hierarchically identifies network device 100 in relation to theother equipment 114 specified by the referent system 108. At the upperhierarchical levels, a country or region 302 can be identified, as wellas a city 304 within that country or region 302. Below these are themiddle hierarchical levels, building structure 202 and floor structure204. Hence, referent system 108 is contemplated to identify a particularfloor of a particular building that is in a particular city of aparticular country.

At the lowest hierarchical level in this example, is device 100 thatexecutes network function 102. This device might be located within aspecific shelf structure 210 that is in a specific bay structure 208, ofa specific aisle structure 206 that is on the floor of the buildingindicated above.

It is understood that the upper hierarchical levels (e.g., 302, 304,etc.) and in some cases the middle levels associated with structures 202and/or 204 can be identified by other referent systems and/or otherlocation-based services such as global position satellite (GPS) or othertrilateration or multi-lateration techniques. Hence, the disclosedsubject matter can be used in combination with other referent systems,generally to identify the higher hierarchical tiers. It is appreciated,however, that the disclosed referent system 108 can describe a locationof a specific device with much greater granularity than can be providedby other location-based services. One of the innovative aspects of thedisclosed referent system 108 is that this precise location can bespecified and/or identified relative to other equipment 114 associatedwith the NFV Network 101, which makes effective use of hierarchy such asthat provided in graphical depiction 300.

With reference now to FIG. 4, illustration 400 is provided. Illustration400 depicts various examples of the referent identifier data 106. Asdetailed previously, referent identifier data 106 can include referencedata 112 that is indicative of other equipment 114 and device data 110that identifies network device 100 relative to the other equipment 114.

In this example, reference data 112 includes four columns of data,indicated as “Location”, “Aisle”, “Bay”, and “Shelf”. It is assumed thatdata associated with the “Location” column sufficiently represents alocation in the context of a specific country, region, city, building,floor, or other pertinent data. Such data can be provided by a differentreferent system (e.g., GPS) and transformed to the example referentsystem 108 depicted here. The subsequent columns, “Aisle”, “Bay”, and“Shelf” can expressly represent other equipment 114, and specificallyelements 206, 208, and 210, respectively. It is understood thatindividual identifiers for these columns can, like device data 110, bean identifier that is relative to other (e.g., higher hierarchical tier)equipment 114.

In some embodiments, and due to the hierarchical nature of examplereferent system 108, device data 110 can be a non-unique identifierwithin referent system 108. Such is illustrated by boxes 402 a and 402b, which both depict the same identifier for two different networkdevices. Similarly, reference data 112 can be a non-unique identifierfor certain other equipment 114, as illustrated by box 404, which bothdescribe in this example the same shelf structure 210, even thoughreferring to different devices within that shelf structure 210. However,referent identifier data 106, which represents a combination of(potentially non-unique) reference data 112 and (potentially non-unique)device data 110 can be unique within referent system 108, as illustratedby box 406. Hence, a precise location of a network device (e.g., networkdevice 100) that does execute or is available to execute a networkfunction (e.g., network function 102) at a particular time can beidentified by referent system 108.

Turning back FIG. 1, in some embodiments, network device 100 candetermine move data 116. Move data 116 can relate to a move associatedwith network function 102. In some embodiments, this move (which can becharacterized and/or facilitated by move data 116) of network function102 can relate to transferring execution of network function 102 fromnetwork device 100 to another network device (not shown) of the NFVnetwork 101. For example, network device 100 can terminate processesrelated to the execution of network function 102 and the other devicecan instantiate processes related to the execution of network function102. It is understood that when network device 100 off-loads thecomputing/processing of network function 102 to the other device, thephysical location of the computing elements that are executing networkfunction 102 has likely changed. Referent identifier data 106 can beupdated to reflect this change. Additionally or alternatively, referentsystem 108 can be accessed in order to specify or select a suitablephysical location or area where network function 102 is to be off-loadedor instantiated, and the execution of network function 102 can be movedto one or more devices at that location or area, as described byreferent system 108.

In some embodiments, move data 116 associated with a move of networkfunction 102 can relate to a change in a physical location associatedwith network device 100. For example, consider a mobile computingplatform that collects data relating to weather events that is moved toavoid adverse weather such as a tornado or hurricane. It is appreciatedthat although the physical device executing network function 102 (e.g.,network device 100) has not changed, the actual physical location ofthat device has changed as a result of the move and these changes can bereflected by an appropriate update to referent identifier data 106and/or selected or determined in advance of the move based on referentsystem 108 (e.g., to select where to move the network device).

It is understood that there are many reasons why network function 102might be moved or why identifying in advance of a move a desirabletarget (e.g., device or location) for the move. For example, certainnetwork functions might be subject to legal, regulatory, or contractualobligations to be executed within specified geographic boundaries or tobe executed at certain local times (e.g., “follow the sun”). As anotherexample, disaster recovery (e.g., weather, political, etc.) events mightlead to a move as might capacity management issues, performancemanagement issues, or equipment failure events.

Regardless of the reasons, moving a network function 102 createsdifficulties for other reference systems. For example, relying on MACaddresses or the like might provide an ID for the device executing anetwork function, but says nothing specific as to the actual physicallocation of that device, particularly after a move. GPS or otherlocation-based services can provide a physical location reference, butrequire additional equipment for devices and often do not providelocation information to the resolution of what might be required formany applications since identifying a city or even a particular buildingor floor can still be insufficient to readily locate a given networkdevice in many instances. Advantageously, the disclosed referent system108 can mitigate certain deficiencies of other reference systems and canprovide for updating appropriate information in response to changes inthe physical location of the device(s) executing network function 102.

Referring now to FIG. 5, system 500 is illustrated. System 500 providesfor a network health monitoring device 502 that can leverage thereferent system 108 to identify a physical location of the networkdevice 100. In some embodiments, network health monitoring device 502can receive status data 504 from network device 100 or from anotherdevice or equipment associated with the NFV Network 101. Receipt ofstatus data 504 can be in accordance with push or pull techniques orbased on a schedule. Put differently, network device 100 can initiatetransmission of status data 504, transmit status data 504 in response toa request (e.g., from network health monitoring device 502), or inaccordance with a schedule.

Status data 504 can include referent identifier data 106 as detailedherein. Furthermore, status data 504 can include various status-baseddata such as, for example, spare capacity message 506 that indicatesnetwork device 100 has spare computing capacity, maintenance message 508that indicates network device 100 requires maintenance, or some othersuitable indication of a state or status associated with network device100. In response to status data 504, network health monitoring device502 can determine location data 510 indicative of a physical location ofnetwork device 100 based on the referent identifier data 106 included instatus data 504.

Turning now to FIG. 6, system 600 is illustrated. System 600 illustratesthe network health monitoring device 502 monitoring a group of devicesassociated with the NFV network 101 and transmitting various indicatorsin response to status data. In this example, network devices 602 canrepresent a group of all or a portion of the devices that provide NFVnetwork 101. The devices of the group of network devices 602 can besubstantially similar to network device 100, as described herein, and/orthe group of network devices 602 can include network device 100.Likewise, status data 604 represent a group of individual statusindicators from all or a portion of the individual network devices 602,any of which can be substantially similar to status data 506 detailedherein. For example, status data 602 can include referent identifier 106for the associated network device 602 and an associated statusindicator.

In response to receiving status data 604, network health monitoringdevice 502 can transmit location data 510 associated with the particularnetwork device(s) 602 and an appropriate status indicator (e.g., 506,508, etc.) to other network elements or devices that can facilitateappropriate action in response.

Moreover, the word “exemplary” is used herein to mean serving as anexample, instance, or illustration. Any aspect or design describedherein as “exemplary” is not necessarily to be construed as preferred oradvantageous over other aspects or designs. Rather, use of the wordexemplary is intended to present concepts in a concrete fashion. As usedin this application, the term “or” is intended to mean an inclusive “or”rather than an exclusive “or”. That is, unless specified otherwise, orclear from context, “X employs A or B” is intended to mean any of thenatural inclusive permutations. That is, if X employs A; X employs B; orX employs both A and B, then “X employs A or B” is satisfied under anyof the foregoing instances. In addition, the articles “a” and “an” asused in this application and the appended claims should generally beconstrued to mean “one or more” unless specified otherwise or clear fromcontext to be directed to a singular form.

In addition, while a particular feature may have been disclosed withrespect to only one of several implementations, such feature may becombined with one or more other features of the other implementations asmay be desired and advantageous for any given or particular application.Furthermore, to the extent that the terms “includes” and “including” andvariants thereof are used in either the detailed description or theclaims, these terms are intended to be inclusive in a manner similar tothe term “comprising.”
